Regression lines (with 95% confidence intervals) demonstrating the correlation between cognitive outcomes and regional FA in d-TGA subjects (panels a and b) or subjects with d-TGA and controls combined (panels c and d), not adjusting for sex. a) WIAT mathematics composite score increases as left parietal FA increases (sex-adjusted Pearson r=0.39, p=0.006). b) Parent Conners ADHD Index T score decreases, indicating fewer ADHD symptoms, as right precentral FA increases (sex-adjusted Pearson r=−0.39, p=0.006). c) Parent Conners ADHD Index T score decreases, indicating fewer ADHD symptoms, as right ACT FA increases (sex-adjusted Pearson r=−0.23, p=0.04). d) TVPS visual closure score increases as right frontal FA increases (sex-adjusted Pearson r=0.23, p=0.04).
